Tietojenkeruu, also known as data collection, is the systematic gathering of information from various sources. This process can be conducted through manual methods, such as surveys and interviews, or automated methods, including web scraping and sensor data collection. The primary goal of data collection is to obtain accurate and relevant information that can be used for analysis, decision-making, and research purposes.

Data collection can be categorized into two main types: primary data collection and secondary data collection. Primary data collection involves gathering new information directly from the source, while secondary data collection involves using existing data that has been collected by someone else. Both methods have their advantages and disadvantages, and the choice between them depends on the specific requirements of the project.

Ethical considerations are crucial in data collection. It is essential to ensure that the data is collected in a fair and transparent manner, respecting the privacy and rights of individuals. This includes obtaining informed consent, protecting sensitive information, and complying with relevant laws and regulations, such as data protection laws.

Data collection is a fundamental step in the data lifecycle, which also includes data cleaning, data analysis, and data visualization. Effective data collection ensures that the subsequent steps in the data lifecycle are based on accurate and reliable information, leading to meaningful insights and informed decisions.
